Answer:

y= x-3

Step-by-step explanation:

use the slope formula which is y= m(slope)x + b(y intercept)

The slope is one, so you can just leave it as x, and the y intercept is -3 so you can plus that into the b.

Hope this helps :)

Kittens weigh about 100 grams when born and gain 7 to 15 grams per day. If a kitten weighed 100 grams at birth and gained 8 gram
tangare [24]
25 days

First, start with an equation

100+8x= kittens weight

(X representing the days)

Since you’re trying to figure out the number of days it takes the kitten to triple it’s weigh you multiply it’s initial weight by 3 (100•3)

Find the percent of the number.<br> 30% of 30 is<br> Explain your method.
nirvana33 [79]

Answer:

The answer would be 9

Step-by-step explanation:

Step 1: Our output value is 30.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$30=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

Step 7: Again, the reciprocal of both sides gives

Therefore, 30% of 30 is 9

Amy is 9 years older than her younger sister. if her younger sister is now 1 year old, how many years later will Amy be 4 times
Sholpan [36]
<h3><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u></h3>

  • Age of Amy's younger sister=1year

☆Amy is 9 years older than her younger sister.

\\ \sf\longmapsto Age\:of\:Amy=1+9=10years

Let after x years Amy will be 4times old as her sister.

ATQ

\\ \sf\longmapsto \dfrac{1+x}{9+x}=\dfrac{1}{4}

  • Using cross multiplication

\\ \sf\longmapsto 4(1+x)=1(9+x)

\\ \sf\longmapsto 4+4x=9+x

\\ \sf\longmapsto 4x-x=9-4

\\ \sf\longmapsto 3x=5

\\ \sf\longmapsto x=\dfrac{5}{3}

\\ \sf\longmapsto x=1.6

\\ \sf\longmapsto x=2(approx)
